WILLIAM B. ALLBRIGIIT, OF CHICAGO, ILLINOIS.

REINFORCED-LOOP BEATER.

Application filed March 13, 19167 To all whom it may concern:

Be it known that 1, WILLIAM B. ALL- mucrrr, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Reinforced-Loop Beaters, and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings. and to the numerals of reference marked thereon, which form a part of this specification.

One of the most successful types of beaters used in carcass dehairing machines is the resilient loop heavy fabric beater provided with metallic scrapers. Practically the only portion of the beater which depreciatesor wears with continued use is the fabric loop, and the other parts of the beater may again be used when the fabric loop is renewed.

This invention relates to a fabric loop beater of an improved construction, somewhat similar to that described in my United States Letters Patent for carcass heaters, No. 1,164,053, issued December 14th, 1915, but differing in that the fabric used to construct the loop is reinforced, thus prolonging the life and increasing the service thereof. The construction and assembly of the parts is also greatly simplified, permitting the same to be readily attached or detached from the machine without inconvenience or loss of time.

It is an object of this invention to construct a carcass beater for use in hog dehairing machines wherein a relatively short loop of reinforced fabric is detachably connected upon metal arms, which are bolted to one another around a shaft.

It it also an object of this invention to constructloops for a carcass beater which are reinforced centrally at their ends, and with the longer or leading sides thereof provided with scraper blades.

It is also an object of this invention to construct a loop beater mounted upon a driving shaft, the loop of said beater being reinforced at the outer curved portions with extra plies of fabric to strengthen and in crease the efficiency thereof.

It is furthermore an object of this invention to construct a beater comprising a loop of heavy fabric reinforced with extra layers of fabric on the inner and outer sides thereof and detachably connected at its ends which Specification of Letters Patent.

Patented Nov. 6, 1917'.

Serial No. 83,780.

are reinforced upon metal arms, and scrapers attached on said loop.

It is finally an object of this invention to construct a. resilient beater comprising loops made up of layers of heavy fabric with extra plies of heavy fabric associated therewith at difierent parts of said loops to reinforce the same, thus lengthening the life of the beater.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

In the drawings:

Figure 1 is a top plan view of one type of beater shown in horizontal position mounted upon a shaft shown fragmentarily.

Fig. 2 is a side view thereof.

Fig. 3 is a section on line 33 of Fig. 1.

Fig. i is a modified type of beater.

Fig. 5 is a fragmentary longitudinal secion at one of the ends of thebeater loop.

Fig. 6 is a similar fragmentary section at the middle of the loop.

Fig. 7 is a section taken on line 77 of Fig. 6.

As shown in the drawings:

The heater, as shown in Figs. 1 and 2, is mounted upon a driving shaft 1, and con sists of semi-circular clamps 2, which are exactly similar in construction and interchangeable. said clamps being held together by bolts 3, on opposite sides of said shaft. A curved attaching plate l, is integrally connected on one side of each of said clamps by means of an angled arm 5.

Ribs 6, are provided on the other side of said clamps to receive the heads of the bolts 3, as the nuts are tightened up. Adjacent the ribs 6, is an abrupt right angled web 7 also formed integrally with said clamps, and integral with said web 7, is an outwardly directed rearwardly curved rigid reinforcing arm 8. A loop 9, madeof plies of relatively stiff fabric 10, is reinforced onthe inner and outer curved surfaces thereof with extra plies of fabric 11, at different lengths vulcanized on or secured to the loop by means of glue, cement or other suitable means to prevent the loop from cracking or breaking at points near the middle thereof. Said loop 9 is bolted at one of its ends between a clamping plate 12, and a relatively stiff short piece of fabric 13, which rests upon the inner portion of said reinforcing arm 8, said members all being rigidly held to said arm 8, by means of bolts 14, extending therethrough.

Ribs. 15, are formed on the surface of said arm 8, to receive the squared heads of the bolts 14:, to prevent rotation thereof, when the nuts are tightened. The other id of said fabric loop is clamped against a flexible reinforcing strip 16, upon said flat plate l, by means of a bolt 17. Riveted or secured in any suitable manner upon the leading side of the loop 9, are metallic scrapers 18, in this instance five being shown symmetrically arranged, but, of course, the arrangement and number may be varied without departing from the principles of this invention.

In the form of device illustrated in Figs. l to 7, inclusive, I have shown a different arrangement of the loop on the beater shaft as well as, and more important, a different construction of the loops themselves.

The fragmentary sectional view shown in Fig. 5, illustrates a portion of the beater loop 19, at one of its ends, showing extra interior plies of fabric 20 and 21, respectively, therein.

Fig. 6. illustrates a fragmentary sectional view of the middle portion of the beater loop showing extra interior plies of fabric and 24:, respectively, which are disposed in a position radially inward of the center plies of the beater loop. The manner in which the fabric is folded over and upon itself whereby the several plies are formed and disposition of the extra inserted plies, is clearly shown in Fig. 7.

The operation as follows:

lVhen it is desired to adjust the beater upon the shaft merely one pair of the bolts 3, are loosened, thus permitting the heaters to be rotated into a preferred position or moved longitudinally upon the shaft. In dismounting a heater from the shaft, the bolts 3, are removed and one set of either of the bolts l l or 17, are loosened whichever are most convenient for the purpose, or if one end of the shaft 1, is free, of course, the beater may be moved longitudinally and taken off at the end thereof. However, one of the principal points of advantage in this particular heater is the fact that the beater loop is reinforced with extra plies to lengthen the service thereof and to prevent the loop from cracking or breaking at those portions which are subjected to the greatest bending stresses.

The means for attaching the beater to the shaft is extremely simple, and the flexible forcement means 8, prevent an abrupt bending of the fabric at any point which tends to break the same and renders it unfit for llswl I am aware that the loop reinforcing means and various other details of construction may be varied through a wide range without departing from the principles of this invention. I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. In a device of the class described, a multi-ply loop of folded flexible material, and inserted plies between the folds at the ends and curved portion of the loop to reinforce the same and prevent breaking.

2. In a multi-ply beater loop of the class described, folded material forming a plurality of plies, and extra plies of material of different lengths secured in the loop formed by the folded material and in the ends of the loop to reinforce the same at the points of greatest bending.

3. In a device of the class described, a beater loop comprising impregnated folded layers of a unitary strip of fabric, and extra plies of short lengths of fabric ass0- ciated with said layers at a plurality of clifferent points to increase the thickness of the loop at points of greatest bending to reinforce the same.

4.. In a multi-ply beater loop of the class described, flexible impregnated material folded to form a plurality of plies, and impregnated plies of fabric laid within the folds of said loops at the ends and middle portions thereof to reinforce the same.

In a heater loop of the class described, a plurality of integrally connected plies of flexible material, and a plurality of extra plies of material of different lengths associated with said beater loop at difierent parts thereof to reinforce the loop at points of greatest bending stress.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.

WILLIAM B. ALLBRIGHT.
